There is a small possibility that some wild birds may be affected by the highly
pathogenic
form of the H5N1 strain of avian influenza in the UK this winter. If you come
across a
suspicious die-off of wild birds please:

Over the last few months, many birdwatchers will have become aware of
considerable
media interest in the subject of avian influenza or 'bird flu', following
outbreaks in central
Asia, Russia and the Black Sea region of the highly pathogenic strain of the
virus – H5N1 –
which developed within poultry.

Representatives of BTO, WWT, RSPB and JNCC have been involved in discussions
with the
relevant government agencies, principally to advise on the latest knowledge of
the origins of
birds wintering in the UK, migration routes and timing, and bird distributions
within the
UK. Such information is derived largely from the hard work of volunteers working
on
schemes such as the BTO Ringing Scheme and the BTO/WWT/RSPB/JNCC Wetland Bird
Survey (WeBS). We have also remained in close contact with international
colleagues.

The overall assessment is that the chance of this strain of the virus being
carried to the UK
by a migrating bird is currently low (and no more likely than the chance of
transmission via
illegally imported poultry and their products, or the wild bird pet trade). In
addition, even if
H5N1 did make it to the UK, it is important to note that this is a disease of
birds, primarily
poultry; that there are no known cases of transmission from wild birds to
humans; in southeast Asia, the virus has (infrequently) infected humans as a
result of close and excessive contact with infected poultry. Thus the risk to
human health from wild birds carrying H5N1 is remote.

Nevertheless, it is clearly sensible to keep the situation under review. A
number of
organisations are working together to deliver a national surveillance programme
for wild
birds on behalf of Defra (for further details see
http://www.defra.gov.uk/animalh/diseases/notifiable/disease/ai/index.htm.)
This will include enhanced monitoring for sick or dead birds, coupled with a
programme of taking faecal samples from a) apparently healthy live birds, and b)
birds shot as part of legal
wildfowling activities.

As part of this process, we would ask birdwatchers in the field to keep an
eye out for any suspicious cases of large-scale mortality or sickness amongst
wild birds. Wildfowl are potentially among the most vulnerable wild birds.
Obviously, all birdwatchers encounter dead birds occasionally, almost all due to
perfectly natural causes, so use your common sense. However, if you should come
across an incident that seems out of the ordinary, this should be reported via
the Government Helpline on 08459 335577 in England, Scotland or Wales or
02890 524999 in Northern Ireland. Calls would then be referred to the relevant
veterinary authority. Specialists at the labs would then make an assessment on
what further action, if any, should be taken.

Although there have been no proven cases of humans catching the disease from
wild birds,
the virus is spread through nasal secretions and faeces, so please do not touch
sick birds or
carcases in the event of a suspicious die-off. Note that separate guidelines
have been
provided to ringers and these will be made available to anyone else who
regularly handles
wild birds. In general, however, to guard against a wide variety of illness,
including avian
influenza, it is always prudent to exercise basic hygiene when coming into close
contact with
wild animals (e.g. washing hands with soap directly afterwards, especially
before eating).

At a time when there is a lot of misinformation on this issue circulating, it is
essential to keep matters in perspective and to sift fact from fiction. We
reiterate that, at present, we consider the chance of wild birds bringing highly
pathogenic H5N1 to the UK to be low and the potential for onwards transmission
from wild birds to people to be very low. Obviously,
however, we are continuing to monitor the situation and if there are any further
developments we will communicate these widely, in the first instance via
organisational
websites.
